Problem-solving is the most important core skill in chemistry, it is what chemistry is all about. Here are the five-step general problem-solving process:
Step 1: Identify What is Given
Separate the problem into the facts, conditions and assumptions. List them symbolically as familiar chemical terms and formulas.
Step 2: Clarify What is Being Asked
Understand what is asked and if unclear, try to rephrase the question in terms that you know.
Step 3: Select a Strategy
Choose an appropriate method to solve the problem. These strategies include trial-and-error search, deduction, working backward and the knowledge-based method. The goal is to establish a path to get to what is being asked from what is given.
Step 4: Solve
Apply the skills and mathematical expressions needed to carry out the strategy chosen.
Step 5: Review
Examine the reasonableness of the solution, and correctness of the units, significant figures and order of magnitude. Fix the possible errors and re-evaluate the approach.
Tip of the Day: Solve chemistry problems systematically using the strategic 5-step process.
